What it is
A phone or tablet. Phones advertise over Bluetooth for nearby-sharing, continuity and accessory features, and over Wi-Fi when hotspot or direct-connect features are on.
Who uses it
Everyone. The dominant kind of emitter anywhere people are.
What it can see
The phone's owner can see a great deal, but the advertisement you hear carries very little: a rotating address and a few feature flags.
What it can't do
Hearing a phone does not reveal who owns it, and most phones rotate their address every few minutes so the same phone looks like a new device.
How Wavelens finds it
BLE manufacturer company IDs and advertisement layouts used by major phone platforms; address type (rotating private addresses are typical); Wi-Fi vendor prefix when the phone is a hotspot.
What to do when you see one
Nothing is required. A phone that pairs with the "following" verdict is far more likely to be a fellow traveller than anything else.
Phone or companion?
The phone alone hears these over Bluetooth and Wi-Fi. A companion adds range, not a new kind of detection.

Classification is a best-effort guess from public signature data. Check before you act on it. None of this is a claim about who owns a device, why it is there, or whether it is lawful.
